Multi-loop crisscross-spanning steel pipe pole

Abstract

The invention relates to a multi-loop crisscross-spanning steel pipe pole which comprises a common pole body, lower-layer loop cross arms, upper-layer loop cross arms and a ground wire cross arm. The lower-layer loop cross arms, the upper-layer loop cross arms and the ground wire cross arm are crisscross, two sides of the common pole body are respectively provided with one circuit transmission line, and the common pole body consists of four vertical steel pipes which are provided with no knick point and connected through flanges. Compared with conventional iron towers, the rigid frame steel pole structure in rigid connection with the cross arms is small in foot distance, the line corridor width is decreased, accordingly the demolition and vegetation deterioration are decreased, and resource saving and environmental protection are facilitated. A traversing tower and a spanning tower are integrated on the combined steel pipe pole, the engineering investment is saved, the power outage time is shortened, a traversing mode is simple and easily implemented in an urban area, line channels and the tower-occupied area are decreased, the overall appearance is attractive, and the multi-loop crisscross-spanning steel pipe pole meets the appearance requirement of urban power transmission lines.

Description

technical field [0001] The invention relates to a cross spanning and crossing tower between power transmission lines, in particular to a multi-circuit cross spanning steel pipe pole. [0002] Background technique [0003] With the rapid development of transmission line construction in urban areas in my country, the requirements for line corridors in economically developed areas are becoming more and more stringent, the site is getting smaller and smaller, and the line corridors are getting narrower and narrower. The problem of line application in urban areas has been alleviated, but with the continuous increase of line density, the frequency and difficulty of crossing and crossing between new and old high-voltage transmission lines are also increasing, which is affected by the rolling revision of land use planning by local governments and Influenced by buildings around the line, the tower needs to occupy a small area and it is difficult to accurately reserve the crossing poin...
